Raise workers' awareness of self-protection, protect the health of vulnerable groups, and prevent the occurrence of occupational diseases. It can partially replace the raw rubber raw materials, reduce production costs and improve the rubber's process performance. The following small series for everyone details the relevant knowledge of recycled rubber.
Waste rubber hazards:
The disposal of waste rubber is one of the serious problems facing people today. In order to meet the ever-increasing performance requirements of materials, rubber develops in the direction of high strength, wear resistance, stability, and aging resistance, but at the same time, it causes the problem that after the disposal of the rubber, it cannot be naturally degraded for a long period of time. A large amount of waste rubber causes plasticity. Pollution (white pollution) is more difficult to deal with black pollution. On the other hand, precious rubber resources are wasted.
Millions of tons of waste rubber are produced every year in the world, and the quantity is so huge. How to handle it effectively has become a problem of general concern to society as a whole. For this reason, in addition to putting away a pile of waste rubber products as fuel, in the 1910s, scientists from all over the world began to study more effective waste rubber recycling technologies. Reclaimed rubber refers to the physical and chemical processes such as crushing, heating, and mechanical treatment of used vulcanized rubber, changing from an elastic state to a plastic and viscous, re-vulcanizable rubber. The essence of the regeneration process is the destruction of the vulcanizate network under the combined effects of heat, oxygen, mechanical action, and the chemical and physical action of the regenerant. The fracture site has both crosslink bonds and macromolecules between the crosslink bonds. key.
Occupational hazards and control of recycled rubber production:
The main production process of reclaimed rubber is to conduct large-scale crushing of waste rubber tires that have been acquired, screening and removal of impurities, and then vulcanization of the vulcanization tanks, followed by pressure-compression machine pressing and refining to become reclaimed rubber. The main occupational hazards in this production process are noise, vibration, dust, benzene, toluene, xylene, sulfur dioxide, and hydrogen sulfide.
1. The base for vibration isolation should be added to the equipment that generates large vibration. To prevent the occurrence of occupational deafness by providing anti-noise earplugs or earmuffs that meet the requirements of hygienic requirements for workers exposed to worksites whose noise intensity exceeds the national occupational health standards.
2. Set up a local dust removal system at the working site of the charging port of the sulfidation tank.
3. Closed management of dust removal facilities for breakers should be strengthened and dust collection pipes should be cleaned in time.
4. Set up a local mechanical exhaust system at the working site of the extruder and the refiner. The exhaust hood should follow the design principles of proper form, correct position, moderate air volume, sufficient strength, and convenient overhaul. Hood speed should be sufficient to inhale the toxic and harmful substances generated during the rubber refining process; ducts should use suitable pipes and be reasonably arranged.
